METHOD OF ORNAMENTING PIPE BOWLS AND THE LIKE Filed Spt. 10, 1956 Patented Oct. 11, 1938 UNITED STATES PATENT OFFICE METHOD OF ORNAMENTING PIPE BOWLS AND THE LIKE 3 Claims.

This invention relates to a method of and means for ornamenting pipe bowls and other articles having curved or angular surfaces for receiving ornamentation.

5 Articles of the nature to which the present invention appertains, are usually formed of wood or fibre, metal, bone, Bakelite, Celluloid, etc., and, in view of the fact that the exterior surfaces are generally curved, it has been praclO tically impossible for any ornamentation to be added to them after the articles have left the factory. For example it has been desired to place monograms or initials on the curved 'surfaces of the bowls of smoking'pipes but neither 13 the wholesaler nor the retailer of pipes has had any facilities whereby letters or other ornamentation could be applied to such surfaces.

An object of the present invention is to provide an equipment for use by the wholesaler or retailer for the purpose of applying letters accurately and securely to the curved or other surfaces of a pipe bowl or the like whether the same be made of wood, fibre or any other material.

A further object is to provide equipment which enables the letters or other ornamentation to, be

applied by anyone with or without skill, the parts' used being simple, easily operated and inexpensive.

A still further object is to provide certain new and novel steps in a method whereby the letters or other ornamentation can be applied and, after being so applied, will be held against accidental removal.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in certain novel details of construction and combinations of parts and in certain new and novel steps in the method hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts and in the steps of the method without Figure 3 illustrates the third step of threading the recesses.

Figure 4 is an elevation of the pipe bowl showing the recesses in position ready to receive the studs for holding the letters or other ornamental 5 portions to the bowl."

Figure 5 is a horizontal section through the bowl after the ornamental portionshave been applied.

, Figure 6 is a section through a portion of the bowl after the applied ornamentations have been burnished so as to lie flat against the curved surface of the bowl. I

Figure 7 shows a modified form of jig.

Figure 8 is a section through a portion of a pipe bowl showing recesses for'receiving inlaid ornamentations.

Figure 9 is an elevation of a slightly modified form of ornamentation prior to being burnished onto the surface to which itis applied, a portion of the structure engaged by the ornamentation being shown in section.

In following out the invention the pipe bowl or other object to be ornamented and which can be of any preferred material having a curved. 2 or other surface which is not flat, has applied to it a jig having openings properly located so as to permit marking of the surface through the openings at those pointsadapted to receive the ornamentation to be applied. This jig can be of any desired material and shape. After the surface has been marked as stated, a suitable drill or boring tool is used for forming recesses at the indicated points, these recesses being of exactly the proper depth. Thereafter a tap is inserted in each recess for forming a thread therein. Following this threading operation, the threaded stem or stud projecting from each letter or other article of ornamentation is forced into the threaded recess leaving the fiat head or ornamental portion bearing against the rounded or other surface of the article to be ornamented. Said head is then burnished so as to be bent back against and conform with the contour of the surface to which it has been applied and bymeans of this last step, the rotation of the stud or screw extending from the head is prevented and the ornamentation cannot become accidently separated from the structure to which is has been applied. Furthermore, if desired, the stud which is preferably in the nature of a screw, can be provided with a cement coating so as to cause it to adhere to the wall of the recess in which it is seated. In finishing the recess by means of the threaded tap, it is 5 the practice to leave the recess of the exact size of the threaded tap to be inserted thereinto so that no. displacement of the material of the pipe bowl or the like will be effected by the stud when inserted.

In carrying out the method stated the jig, one form of which has been indicated at I, can be made of any desired material. It can be a thin resilient plate having hooked arms 2 extending therefrom for engaging the edges of a pipe bowl B. Properly positioned holes 3 can be formed in the jig so that the surface of the bowl can be marked accurately at points adapted to be drilled. After the jig has been forced tightly against the surface to be ornamented and said surface hasbeen marked through the holes 3, the jig is removed and there is then used a drill one form of which has been shown in Figure 2. This tool includes a stem 4 having a handle 5 by means of which it can be rotated readily and seated in the stem is the shank 6 of a bit 1.. A stop 8 is mounted on the bit and against the end of stem 4 and serves to prevent the bit from boring a hole which is too deep. In other words that portion of the bit extending beyond the stop 8 will produce a recess of exactly the correct depth.

Following the drilling operation which is effected at each point previously marked on the pipe bowl, a threading tap 9 is placed in engagement with the shank of a threading tool having a handle H. Or, if desired, this tool Ill-ll can be the same as tool 45. The threading tap is likewise provided with a stop I2 similar to stop 9, whereby the movement of the tap into the bowl is limited. The tap is so proportioned as to produce a thread in the recess [3 formed in the bowl.

The ornamentations used on the bowl or other structure can be in the form of thin metal letters, monograms, insignia, etc. In any case the ornamentation, which has been indicated generally at I4, has one or more studs projecting therefrom. When a threaded recess l3 is provided in the bowl, each stud is of the same size as the recess adapted to receive it. Therefore each stud can bescrewed into the recess provided therefor without causing any displacement of the material of the bowl B. Before inserting this stud or screw a coating of cement can be applied thereto so that after the stud has been properly seated, it will adhere to the wall of the recess.

Following the insertion of the stud the head M will bear against the bowl but will not lie tightly against it. In order to complete the application of the ornamentation, it is desirable to burnish the head l4 so that it will press back at all, points against the surface of the bowl as shown in Figure 6. Consequently this head, by its tight engagement with the surface of the bowl, will act as a lock to prevent the stud or screw I of the head from being unscrewed. Therefore danger of accidental displacement of the, ornamentation is avoided.

While screw-shaped studs can be used on the applied ornaments, it is to. be understood that many other types of lugs suitable for holding the ornamentation to the bowl might be employed following the formation and proper shaping of the recesses designed to. receive them.

It is to be understood furthermore that instead of providing ajig such as has been illustrated, the jig could bev in the form of a flexible band to be strapped about the bowl or other object to be ornamented. One jig of this type has been illustrated in Figure 7 wherein hingedly connected plates l6 are carried by straps l1 adapted to be secured about the bowl or other object by means of a buckle I8 or the like. Each plate can be provided with an opening through which the location of the ornamentation can be marked. Or, if desired, these openings, indicated at 19 in Figure 7, can be shaped like ornamentations which are to be inlaid in the bowl and by means of these openings l9, it is possible to use the jig as a guide for cutting the recesses 20 in which the ornamentations are to be inlaid. Under these conditions a suitable cement is applied for fastening each letter or other ornamentation in the recess provided therefor.

Obviously many other designs of jigs could be used. The feature of prime importance in the present invention is found in the fact that the simple and efficient equipment herein described can be supplied to wholesalers and retailers who are thereby enabled readily to apply different kinds of initials, monograms, etc., to pipe bowls and other small articles sold by them and which have curved or angular surfaces which heretofore have prevented the ordinary dealer from applying any particular combination of letters or other ornamentations to meet special orders.

Another modification of the invention has been disclosed in Figure 9 wherein the head 2| constituting the ornamentation to be applied and which is mounted on the stud or screw 22, is made concave and is provided with asupplemental spur 23. Thus after this device has been applied to the bowl B or other structure, the head 2| is burnished as hereto-fore explained and during this latter operation the spur 23 on the head will enter a small recess ornotch 24, provided therefor. Therefore even though the ornamentation should be applied to a flat surface, it will be held in position.

What is claimed is:

1., The method of applying ornamentation to the curved surface of an object which includes the step of marking said surface, recessing the surface at the marked point, threading the recess, inserting in. the recess a threaded stud extending from the head of the ornamentation and then burnishing the ornamentation to conform to the curved surface of the object and hold the stud against rotation in the recess in which it is seated.

2. The method of applying ornamentation to the curved surface of a smoking. pipe or the like which includes the step of recessing said surface to a predetermined depth, subsequently threading the recess, seating in the recess a cement coated stud having an ornamental head provided with a spur, and thereafterburnishing the head to. fit it snugly against the curved surface and to force the spur thereinto.

3. The herein described method of applying ornamentation to a substantially cylindrical or other surfacev which is not flat, which includes the step of marking the surface, forming a recess in the surface at the marked point, placing an ornamentation in the recess, and thereafter burnishing the ornamentation to conform to the contour of the surface in which it is seated.
